MACHINE-SEWED BOOT OR SHOE.

SPECIFICATION forming part or" Letters Patent No. 318,878, dated May 26, 1885.

Application tiled January 19, 1885. (No model.)

To @ZZ whom it may concern:

Be it known that I, LUTHER DAY, of Haverhill, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machine-Sewed Boots and Shoes, of which the following is a specifica-tion.

lThis invention relates to maehine-sewed boots and shoes in which the stitches connecting the outer sole to the upper and inner sole are laid in a channel formed in the outer sole. r

The invention has for its object to enable the outer surface ofthe outer sole to be brought to a thin edge to give the sole a neat appearance without cutting away any of the outer surface of the sole, the grain surface of the outer sole being extended to the edge of the sole as when the edge is not reduced in thickness. Y

To this end my invention consists in the improvement which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure l represents a sectional view of an outer sole having my improvement. Fig. represents a sectional view of a. shoe before the iiap is cemented down. Fig. 3 represents a similar view with the flap cemented down.

rIhe saine letters of reference indicate the same parts in all the figures.

In the drawings, a represents the outer sole; b, the inner sole, and c the upper. The outer sole has the usual stitch-receiving channel, d, and channel-covering tlap e, the latter extending to the edge of the sole, as shown.

In carrying out my invention I cut away the sole between its inner or fiesh surface and the iilap, so as to forni a sloping surface, f, from the channel to the margin of the sole, thus bringing the margin of the sole above the tiap to a thin edge. After stitching the outer sole to the upper and inner soie in the usual manner I cement the iiap to the sloping surface f, as shown in Fig. 3, thus giving the outer or grain surface of the sole a slope from its tread or wearing portion to its reduced edge, the grain surface being thus carried to the edge of the sole.

Heretofore in boots and shoes in which the outer sole has been brought to a thin edge at its margin the desired result has been produced by trimming off a portion of the outer surface of the outer sole along the edge thereof, thus removing a portion of the grain surface. The texture of the grain surface is finer and is capable of receiving a better finish than that of the portion of the leather exposed by cutting away the grain surface. I am therefore able to nish the sloping surface either by burnishing it in its natural color or by bufiing it, or in any desired way, giving it, if desired, the same finish as that imparted to the main portion of the outer surface of the sole. Vhen the sole is reduced by cutting away the grain surface, the reduced portion, presenting the coarser inner texture of the leather, requires to be colored and burnished and cannot be buffed like the grain surface. The reduced portion cannottherefore be made uniform with the main portion of the outer surface of the sole as it can by my improvement.

The knife that forms the channel and fiap may also form the sloping surfacef.

I claim- In a boot or shoe, an outer sole cut from its edge to form a channel-Hap, and cut away or beveled between the channel-flap and the inner surface of the sole, to forni a sloping surface, and having the flap cemented to said surface, as set forth.

In testimony whereof I have signed my name to this specication, in the presence of two subscribing witnesses, this 7th day of January, 1885.

LUTHER DAY.
